Understanding the stages and pathways of travel behavior change induced by technology-based intervention among university students

The authors describe how a mobility behavior change support system, called Blaze, is able to achieve a shift in changing the travel behavior of university students. The authors identify a causal pathway linking the effect of the technology intervention to its behavioral outcome through the mediation of a number of variables. The stage model of self-regulated behavioral change (SSBC) is used as a theoretical framework to understand how the outcome may be influenced by determinants (conceptual theory), and how the determinants may be activated by different intervention types (action theory). Using longitudinal data from a social experiment conducted over a month at a university in the Philippines, the authors test three hypotheses regarding the mechanism of change induced by Blaze. Their main findings suggest, in agreement with SSBC, that travel behavior change is achieved by a transition through a temporal sequence of four stages: predecision, pre-action, action and post-action. In an extension from SSBC, the authors further distinguish post-action depending on whether the behavior is on initiation or under maintenance. They observe that the former (initiation) is characterized by instability (either relapse or progress), while the latter (maintenance) by stability. Moreover, the authors validate most of the determinants of intentions as postulated by the stage model. Finally, they find that that Blaze can significantly change only the proximate implementation intention and not the more distal ones (e.g. goal and behavioral intentions). The authors discuss the implications of their results on the potential role of technology interventions in mobility management.
